Title: Improvements in or relating to time controlled mechanisms
Inventor: BOWEN TOM
IPC: G04F3/02
Filed: 1959-01-21
Abstract: 937,451. Valves. S. SMITH & SONS (ENGLAND) Ltd. Jan. 11, 1960 [Jan. 21, 1959], No. 2323/59. Class 135. A clockwork driven cam mechanism for actuating a valve in one direction, i.e. the opening or closing direction after a first pre-set delay period and actuating it in the opposite direction after a further pre-set delay period comprises two relatively adjustable cams and two cam followers carried respectively by two levers which control the valve actuator. In the first example, Fig. 1, the mechanism controls the pilot valve of a gas cooker. A cam 4 is fixed to an arbor 3 to which is anchored one end of a mainspring which drives through a slipping clutch an escapement controlled train. The second cam 15 is coaxial with the cam 4 and is driven from the shaft 3 through a lost motion and friction coupling 8, 5, 2 and the gear train 10, 11, 13, 14. The lost motion coupling allows the cams to be moved relatively to each other during setting by a knob 1, the settings being indicated by corresponding indicator discs 32, 36, Fig. 3. The disc 36 rotates with the arbor 3 and the disc 32 is connected to the knob 1 by a helical spring, not shown. A follower 17, Fig. 1, on a lever 18 rides the cam 4 and a follower 19 on a lever 20 rides the cam 15 under the bias of a spring 22, the levers 18 and 20 having a common pivot 21. The end 24 of the lever 20 actuates a plunger 29 of a spring-loaded ball pilot valve 25 which controls a main gas supply valve. The lever 18 has an extension 23 adjacent the end 24 of the lever 20. The arrangement is such that at the end of the first preset delay period the follower 19 drops into a recess 16 of the cam 15 and the end 24 of the lever 19 actuates the plunger 29 to close the pilot valve 25 so causing opening of the main gas supply valve of the cooker. At the end of a further delay period the follower 17 drops into a recess 4a of the cam 4 and the extension 23 of the lever 18 retracts the end 24 of the lever 20 from the plunger 29 so that the pilot valve 25 is opened by its loading spring to cause the main gas supply valve to close. The main gas supply valve may be opened by rotating the knob 1 counterclockwise from its datum position. In another example, each of the cams is formed of two parts interconnected by a pin-and-slot and the levers carrying the cam followers control the plunger of the main gas supply valve.

Abstract: 190,656. Inglis, J. N. Jan. 26, 1922. Bakers' ovens.-A travelling oven is adapted for baking close set or batch bread by means of setters removably secured to the plates or trays of the conveyer. A socket 2 of dovetail form is secured to each end of the plate 3, and into this fits a member 4 projecting from the back of the " setter " 1.

In another construction the "setter" slips over two upstanding rods on the plate, and it may be spaced both from the rods and the plate by interposing a layer of insulating material. Alternatively the plate may have upturned ends, to which the " setters " are bolted.

Filed: 1939-01-24
Abstract: 525,557. Automatic volume control. HALSEY, R. J. Jan. 24, 1939, No. 2466. [Class 40 (iv)] In a transmission system comprising a volume range compression device at one point and an expansion device at another point utilizing similar non-linear impedances controlled by the signals at the two points, the non-linear impedances of the two devices are so disposed and their associated circuit impedances so inter-related that the laws of the devices are inverse Figs. 1 and 2 show generalized circuits of the two devices in which f(e) are the non-linear impedances, e being the signal voltage, Z1 and Z3 the input impedances, and Z2-Z5 other associated impedances, and the Specification shows that for inverse laws, Z5 =Z1 +Z2 and Z2= (Z3+Z4)Z5/Z3+Z4+Z5 If f(e) decreases with increase of e, Figs. 1 and 2- operate as a compresser and expander respec, tively, but if f(e) increases with increase of (e) the functions of the two devices are reversed. Tn one arrangement, Figs. 3 and 4 (not shown), the non-linear impedances are dry contact rectifiers connected in shunt and series with the transmission path as indicated in Figs. 1 and 2. In the thermionic valve circuits shown in Figs. 5 and 6, the input impedance of the compresser comprises a high impedance valve 36, Fig. 5, such as a pentode, compression being obtained by a shunt on the output circuit comprising resistance 37 and a transformer 38 having non-linear impedances 40 connected across its secondary winding. Control voltage for the impedances 40 is derived from the output of the compresser by means of a balanced transformer 46 in order to avoid feed-back into the transmission path. In the expander, the input impedance comprises a low impedance triode 54, and the non-linear impedances 58 are effectively in series in the transmission path, control voltage being derived from a differential transformer at the input. In order that the input impedances of the compressor and expander may be very high and very low respectively in comparison with the non-linear impedances, suitable negative feed-back circuits may be applied to valves 36, 54. The control voltages may be derived from the input of the compressor and output of the expander.

[Class 40 (iv).] Relates to pianofortes wherein the strings are electromagnetically vibrated to produce a sostenuto effect, the key contact 16, Fig. 1, being in circuit with the electromagnet 13, with a pulsator 14 (comprising granular carbon separating two electrodes one of which is directly or indirectly connected to the string 10), and with a battery 15, and consists in mounting the second electrode in a non-resonant manner. In Fig. 2 the first electrode is carried in a fibre sleeve 23 on a bar 21 notched at one end 22 to engage the vibrating string and suspended at the other end by an adjustable cord 27. The second, preferably more massive, electrode 19 is sheathed in felt or the like 24 partly inserted in the sleeve 23 and resting on a pad 26 on the bar 21 to which it is bound by yarn 25. In Figs. 4, 5 (not shown) both electrodes are encased in a common felt sleeve, and electrode 18 is directly connected to the string. In Fig. 6 (not shown) electrode 19 is wrapped with yarn within a fibre sleeve. In Fig. 11, the pulsator is arranged vertically, and. electrode 19 rests freely on the carbon granules 20 within a fibre sleeve 23<1>. Wadding may be interposed between the electrode 19 and sleeve 23<1> (Fig. 14, not shown), and the electrode 19 may be grooved to hold the wadding in place (Fig. 15, not shown). In Fig. 17, electrode 19 is spherical, ensuring the same area of contact with the granules 20 should it become tilted. The electrode 18 is mounted on a celluloid blade 40 connected by a wool or silk loop 44 to the string (or tri-chord strings) 10 near the upper bridge, the loop 44 being adjustable along the string to obtain exact synchronism. In Fig. 19, the pulsator 14 is carried on a bent wire arm 50 whose vertical end lies in a groove in the face of one of two clamping nuts on the screwed stud 58 ; the pulsator may thus be secured in different positions in a horizontal plane. The wire loop 60 connecting the vertical end of the arm 50 to the string 10 may be adjusted by moving its ends along the arm or string. The electrodes 18, 19 may be spaced apart by a felt disc, within perforations in which the carbon granules lie. The granules are arranged loosely in the pulsators to provide self-renewing contact-faces.
